[POWERSHELL] Read-Host priority

PowerShell Help
1

Hello,

I have one question because i don’t understand why.

I have realized an array like this :

$table =@([pscustomobject]@{Commentaire = ‘’})
$path = c:\test\test.txt
$Data = Get-Content -Path $path
$comment = $Data[0].Split(“`r”)

$table[0].Commentaire = $comment
$table

and the display is like this :

Commentaire

<hr />

contents of the .txt

second content of .txt

 

But when after the code above I add this ligne : Read-Host “Something”

when i start the script my table don’t appear and when I remove Read-host

that works perfectly I don’t know why have you an idea ? thanks you

Are you trying to display a comment before the Read-Host?

$table =[pscustomobject]@{Commentaire = 'This is my content'}

$table.Commentaire
Read-Host "What is up?"

Output:

This is my content
What is up?: The sky
The sky

Or you can additionally concatenate the string with line breaks:

Read-Host ("{0}rnrnWhat is up?" -f $table.Commentaire)

This is my content

What is up?: The moon
The moon

[/quote] I'm trying to display the comment in a file .txt in my array like this picture ( random pic on google) :

804×197 16.2 KB

But my comment is put instead of User1, User2…

 

I tried to put my code before the read-Host but it pass in first i don’t know why.

The last solution that you propose don’t correspond for what I want because i want to display $Table before read-Host so i can’t concatenateI think

I think perhaps it is something similar to write-host. Write-host goes directly to the console, which can make it show up before other write-output commands that were executed long before write-host. Take this example

write-output (get-date | select * | gm)
write-host "test"

When the command write-output is called, it takes a split second to calculate the output. Therefore the actual output shows up reverse of the order one might expect.

As opposed to this

write-output (get-date)
write-host "test"

test

If this is the case, perhaps you can assign it to a variable and then output it when you’re ready. (just remember write-host nuance)

$userinput = Read-Host -Prompt "Enter some input"
write-host $userinput

Yes that is exactly the problem the Read-Host is realized before my Table but when I enter any character when the Read-Host ask i Have in first what I have typing when the Read-Host asking me and in the second my table that is exactly the exemple that you give with Write-Host.

But I tried to do :

$choice = Read-Host -Prompt “test verify display :”

Write-Host $choice

But that doesn’t fix the problem like you said there is always the nuance

Do write-information or write-verbose instead of write-host

[/quote]
I tried the two of them but no one work there is no way to resolve it or we can’t use a similar fonction of Read-Host ?

8

Try write-output then. It may clutter your output.

9

I just tried and that doesn’t work too the display is always after the read-Host

 

EDIT : I found a way to bypass the problem I have added another Read-Host before the first that doesn’t resolve the problem but that allow to bypass it.
